Rand: Price increases likely will hurt commissaries →
From an article in this week's Air Force Times:
Estimates suggest that a 1 percent change in prices will result in a greater than 1 percent change in the amount of products sold by stores, the researchers said.
"If these findings hold true for a change in the price of goods sold at commissaries, then an increase in prices will decrease revenues," the report stated.
Sounds like elasticity to me.
